The comparison of the possibility of basings with CXs situation is a red herring.
For example : HK based CX F/Os get around 20K AUD/month including housing and pay 15% tax, Oz based F/Os get ( very roughly ) half that and pay 30% tax. ( Cx is the big winner )120-140K AUD/month is still very respectible F/O income in Oz.
How will the EK pay look when taxed at 30% ( using Oz as example ) ? Or do you think they will pay you more to live in your home country ?
Stealth, like many of us who leave for " greener " pastures, few of us realise, or want to believe, what we are in for and once you have vacated Oz, it's very difficult to get back without a mouldy blue shirt in you wardrobe. As an aside I believe you can be arrested and jailed for industrial action in UAE.
